4# The user-driven targets are:
5#
6# universe            - *Really* build *everything* (buildworld and
7#                       all kernels on all architectures).
8# buildworld          - Rebuild *everything*, including glue to help do
9#                       upgrades.
10# installworld        - Install everything built by "buildworld".
11# world               - buildworld + installworld.
12# buildkernel         - Rebuild the kernel and the kernel-modules.
13# installkernel       - Install the kernel and the kernel-modules.
14# installkernel.debug
15# reinstallkernel     - Reinstall the kernel and the kernel-modules.
16# reinstallkernel.debug
17# kernel              - buildkernel + installkernel.
18# update              - Convenient way to update your source tree (cvs).
19#
20# This makefile is simple by design. The FreeBSD make automatically reads
21# the /usr/share/mk/sys.mk unless the -m argument is specified on the
22# command line. By keeping this makefile simple, it doesn't matter too
23# much how different the installed mk files are from those in the source
24# tree. This makefile executes a child make process, forcing it to use
25# the mk files from the source tree which are supposed to DTRT.
26#
27# The user-driven targets (as listed above) are implemented in Makefile.inc1.
28#
29# If you want to build your system from source be sure that /usr/obj has
30# at least 400MB of diskspace available.
31#
32# For individuals wanting to build from the sources currently on their
33# system, the simple instructions are:
34#
35# 1.  `cd /usr/src'  (or to the directory containing your source tree).
36# 2.  `make world'
37#
38# For individuals wanting to upgrade their sources (even if only a
39# delta of a few days):
40#
41# 1.  `cd /usr/src'       (or to the directory containing your source tree).
42# 2.  `make buildworld'
43# 3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
44# 4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
45# 5.  `reboot'        (in single user mode: boot -s from the loader prompt).
46# 6.  `mergemaster -p'
47# 7.  `make installworld'
48# 8.  `mergemaster'
49# 9.  `reboot'
50#
51# See src/UPDATING `COMMON ITEMS' for more complete information.
52#
53# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can
54# cross build world for other architectures using the buildworld target,
55# and once the world is built you can cross build a kernel using the
56# buildkernel target.
57#
58# Define the user-driven targets. These are listed here in alphabetical
59# order, but that's not important.
60#
61# Targets that begin with underscore are internal targets intended for
62# developer convenience only.  They are intentionally not documented and
63# completely subject to change without notice.
